The Environment Act outlines the environmental assessment and licensing process for developments in Manitoba that may have potential for significant environmental and / or human health effects. The process exists to ensure environmental and human health protection, encourage early consultation, allow for full public participation, and ensure economic development occurs in an environmentally responsible manner.

The Classes of Development Regulation (Manitoba Regulation 164/88) lists the types of projects which are defined as developments. Developments must undergo the environmental assessment and licensing process and receive an Environment Act Licence prior to construction and operation. Proponents are advised to contact the Environmental Approvals Branch (EAB) if unsure whether a project is a development. If a project is not a development, proponents are advised to contact the regional department office in the project area to review any other requirements.
